Preston Tucker's Motorcycle!

[Tuckerfan1053]

Not really his, but one which uses a hydrostatic drive transmission like he originally wanted to do with his car.

This bike belongs to Jeff who built it about 3 years ago but I never saw it until I was looking for information on diesels and ran across their website, Hydraulic Innovations. This bike has a custom built frame and mounts a Kubota 3 cylinder diesel engine but what makes the bike even more unique is the hydrostatic drive system, no belts, no chains, no gear drive transmission just hydraulic pumps and motors. Neat.

You still control speed with a twist grip and there’s a front brake lever on the right but the “clutch” lever actually opens a bypass valve to let hydraulic fluid recirculate instead of driving the bike. There is only one foot lever on the right side which has a sort of neutral position in the center, pushing it forward gets the bike in forward motion and pushing it to the rear actually can reverse the bike. Jeff says, theoretically it could go as fast in reverse as forward but he limited the speed to prevent things from getting out of hand.
